Step-by-step solution

Benzoyl chloride is hydrogenated over catalyst, palladium on barium sulphate. This reaction is called Rosenmund reduction. Nitriles are reduced to corresponding imine with stannous chloride in the presence of hydrochloric acid, which on hydrolysis give corresponding aldehyde. This is named as Stephen reaction Use of Chromyl chloride oxidises methyl group to a chromium complex, which on hydrolysis gives corresponding benzaldehyde.This is called etard reaction When benzene or its derivative is treated with carbon mon
